Abstract: PURPOSE:To photograph a serial number normally by permitting the increase or the decrease in numeral for photographing for the first time when the winding quantity of a film comes to be a prescribed quantity or above at the time of exchanging the film. CONSTITUTION:The means to output the signal to show whether or not the winding quantity of the charged film is the prescribed quantity or above, in which the normal photographing is assured, is provided. It is determined whether the increase or the decrease in the numeric for photographing is permitted or prohibited in accordance with the signal, and only during the film empty feeding period, the increase or the decrease in the numeral for the photographing is stopped automatically. Consequently, the complicated operation that the change-over switch to change over whether or not data photographing is executed is changed over to the off position only for the film empty feeding period is not necessary and the operability is improved.

Abstract: PURPOSE:To use a displaying means in common and to easily confirm visually an exposure control mode name and an exposure control data by changing over and controlling in accordance with the manual operation whether a character string to show a exposure control mode is displayed or the exposure control data are displayed to a displaying means. CONSTITUTION:The device has a displaying means to use and display the character and the numeric value, for example, have the segment group of plural digits of the dot matrix, and a displaying control means to change-over and display the numeric value of the character string and the exposure control data to show the exposure control mode, on the displaying means in accordance with the manual operation. Thus, the character column and the exposure control data to show the exposure control mode can be used and displayed at the same displaying part. Consequently, by the exposure control mode name and the exposure control data, the area of the displaying part is made relatively larger than the conventional displaying means to need the separate displaying part, and the displaying contents can be easily confirmed visually.

Abstract: PURPOSE:To obtain plural exposure arithmetic functions by providing both a camera body and an adapter for exposure control with the exposure arithmetic functions, and performing exposure control on the basis of the arithmetic result of the camera body when no arithmetic result is sent out of the adapter. CONSTITUTION:A switch S2 is a release switch which is closed by the 2nd stage of depression of a release button and when the S2 is closed, exposure control operation is started. Further, a signal line BS2 is connected from a back circuit BCKC in parallel to it and a signal for starting photographing operation is sent to the camera body when a specific number of photographs are taken under the control of the BCKC as interval photography or while the exposure is deviated from proper exposure by a constant value at each time. Further, the BCKC checks the state of the S2 of the camera body and sends data which inhibits exposure control operation from being entered to the camera body unless the S2 is on after the number of set frames are exposed by bracket photography. Consequently, photography is performed in a photographic mode that the camera body does not have.

Abstract: PURPOSE:To shorten the time required for setting the next photographing ready condition not only for one frame photographing, but for low-speed continuous photgraphing without using any circuit of a different system, by providing a circit which generates an exposure operation inhibiting signal and generating the signal under a condition corresponding to the photographing mode of one frame photographing, low-speed continuous photographing, etc. CONSTITUTION:In the case of low-speed continuous photographing, a switch SM1 is turned on and another switch SM2 is turned off. Because of the switch SM2 being turned off, the output of an OR2 is always high. On the other hand, since the bottom terminal of an OR1 becomes low, output of the OR1 becomes high only when its top terminal becomes high under a certain condition. When the certain condition is set while a switch S2 is turned on, an i2 becomes high. The certain condition is that a switch S4 is turned off after film forwarding original operation is complete and a capacitor C1 is discharged through resistances R3 and R4, and then, the (a) point rises to a certain threshold and top terminal of OR1 becomes high in level. Under a low mode, the time required by the i2 becoming high is delayed by the delaying operation of the circuit composed of the capacitor C1 and resistance R3 and R4 and the interval is prolonged by the delayed time.

Abstract: PURPOSE:To simplify the starting operation by starting one of a camera body and a camera accessory in response to starting of the other when the other is started by the manual operation. CONSTITUTION:When a switch S1 of a camera body BD is turned on by the manual operation, the low level is inputted to a signal line of a camera control circuit BMC to start the circuit BMC. When the circuit BMC is started, it sets a signal line CSB to the low level. When the line CSB is set to the low level, a gate circuit G2 is opened to make is possible to transmit and receive data between the body BD and a camera accessory BCKC, and the signal on the line CSB starts an accessory control circuit of the accessory BCKC. Meanwhile, a signal in the low level is given to terminals T2 and T7 of the body BD from the accessory control circuit when this circuit is started by the manual operation. Then, the gate G2 is opened and the circuit BMC is started.

Abstract: PURPOSE:To receive many data with a small number of terminals by sending data indicating a used film sensitivity value to a data imprinting device from a camera body as serial data. CONSTITUTION:When the imprinting function is selected, a back circuit BCKC starts the data imprinting operation. The camera body outputs a pulse having a time width corresponding to the film sensitivity ot a serial data input terminal T3 of the back circuit BCKC as serial data. A control microcomputer CMC generates data having the time width read from the camera body. When sending of an exposure time and an aperture value for control from the camera body is detected, a synchronizing signal is sent to a driving circuit LDR of an imprinting LED through a signal line CSLD for said time width to drive the LED dynamically, and data is imprinted. By this constitution, many kinds of film sensitivity data are received without increasing the number of terminals.

Abstract: PURPOSE:To enable multiple exposure of desired times to be accomplished accurately by providing a multiple exposure times setting dial, a multiple exposure operating member and an actuating member. CONSTITUTION:Multiple exposure (n) times are beforehand determined, and the figure of the desired times (n) of a multiple exposure scale 153 is matched to an index 154 by using a multiple exposure times setting dial 151. When a multiple exposure botton 161 is slided in direction of the arrow, said button 154 pushes the bent part 163a of a multiple exposure lever 163, thereby turning the levers 163, 165 counterclockwise. As a result, an operating shaft 171 for operating rewinding button is pushed up to push the rewinding button of the camera body, by which the camera body is shifted to a multiple exposure ready state. When this preparation is over, the camera release operating member is operated. A release signal is emitted from a timer circuit, and multiple exposure is performed here.

Abstract: PURPOSE:To evade the application of tensile load on a film for a long time by constituting gear trains of 1st gear trains on the side of a motor and 2nd gear trains on the side of a coupler, detecting the reverse rotation when each gear of the 2nd gear train rotates reversely, and stopping the drive of the motor. CONSTITUTION:When a winding-up motor 11 rotates, tailing end gears 19 in the 1st gear trains 12-19 rotate together with a winding-up transmission roller 26, thereby rotating gears in the 2nd gear trains 20-23. When the winding-up of the film stops on the side of the camera main body on the way of winding up the final frame of the film, the roller 26 rides on the projecting part 28a of a cam 28. At the completion of the riding on, force that the roller 26 presses the cam 28 is released, and tensile force etc. fed to the film reversely rotates gears of the 2nd gear trains 20-23. A signal from a reverse rotation detecting means detecting the reverse rotation stops the motor. Thus, such a state that the high tensile strength is applied to the film in a long time when the winding-up of the film stops, especially at the initial stage of winding the final frame of the film is evaded.
