Abstract: PROBLEM TO BE SOLVED: To display program guide information quickly. SOLUTION: A paraboloidal antenna 2 acquires a broadcast radio wave sent from a broadcast satellite 3 and gives it to a turner section 4. The turner section 4 receives a channel in response to the setting of a reception channel setting means 1a and divides the channel into pluralities of packets and provides an output of them. A broadcast signal input means 1b receives the packets outputted from the tuner section 4. A packet composite means 1c composites the packets supplied from the broadcast signal input means 1b to produce the original broadcast signal. A program guide information storage means 1d stores program guide information when the received broadcast signal is the program guide information. A program information storage means 1e stores the received broadcast signal when the signal is a conventional program. A retrieval means 1f retrieves an item corresponding to a retrieval condition entered by an entry section 6 from the program guide information storage means 1d and outputs it to an output means 1g. The output means 1g displays the retrieval result fed from the retrieval means 1f on a display device 5.

Abstract: PROBLEM TO BE SOLVED: To accurately level the height of a reel base holding member with a simple constitution without using a clamping member for leveling the height and to evade backlash in the height direction. SOLUTION: In the recording and reproducing device such as a VCR device, etc., capable of changing a space between two reel bases 1 and 2 by a reel base moving mechanism 43 and selectively mounting large and small different sized tape cassettes on the reel bases 1 and 2, to the reel base holding member 26, a fulcrum shaft 24 is fixed to be a turning fulcrum as a height leveling means of the reel base holding member 26 for supporting the reel bases 1 and 2, and is rotatably supported by a mechanical chassis 3. Then, a fitting seat 32 of a height leveling pin 31 of the cassette supported by the reel base holding member 26 is brought into slide contact with the surface of the mechanical chassis as a height leveling member, and the reel base holding member is energized to be pulled to the side of the mechanical chassis by a leaf spring member 37 via the fulcrum shaft 24, thus the height of the reel base holding member as against the mechanism chassis is leveled.

Abstract: PURPOSE:To enable the use of large and small cassettes by forming engaging notched parts on an abutting part for positioning the small cassette and the lower edge of the front surface of a cover. CONSTITUTION:When the tape cassette T is loaded on a recording/reproducing device, the abutting part for positioning the small tape cassette abuts on the front surface 16a of the part 16 to be abutted, and the abutting part 46 for positioning the large tape cassette abuts on the front surface 15a of the part to be abutted, then the cassette T is positioned. In the closed state of the cover 21, the lower end part on the front surface part 25 of a front lid 22 is abutted on the front surface of the part 17 of a lower half 4, therefore, the extensive deflection does not occur and there is no unrest in the strength since the front surface 25 abuts on the part 17 even through it is pressed from the front side. Since the notched part on the front surface part 25 of the front lid 22 is engaged with the abutting parts 15, 16 of a case 2 and the half 4 is located at the back side between the notched parts 30, 31, the space produced when the cover 21 is slightly moved is limited to the small extent, so the dust-proof property is almost not impaired. Thus, the stable positioning is executed and also the dust proof-property is ensured.
