Description

[Detailed Description of the Invention] The present invention relates to a composite device in which a push-button tuner is incorporated into a tape player, and in particular, to eliminate erroneous indication of the tape feeding direction.

Conventionally, when a channel selection member is pressed, a variable tuning element is varied to select a station, and the push button is held in an immersed state, and this immersed state is automatically restored when another channel selection member is pressed. The push-button tuner thus constructed is incorporated into a tape player to constitute a composite device, and each operating mechanism in the tape player and each tuning member in the push-button tuner are made to face each other, so that when the tuning member is in the retracted state, A composite device configured to maintain the operation mechanism of an opposing tape player in an operating state is known, for example, from Japanese Utility Model Publication No. 57-5755.

However, according to the composite device in this configuration,
Since the push-button tuner is configured to hold the tuning member in an immersed state, for example, as shown in Japanese Patent Publication No. 55-20480, a stored drive and control program can be selected by operating a switch to operate the tape player. When constructing a composite device by incorporating the push-button tuner into a tape player including a logic control circuit for drive and control, and operating the opposing switch with the channel selection member in the retracted state,
Since the switch is held in a pressed state,
For example, when the switch facing the channel selection member is for operating the A side of the tape, the display mark corresponding to the position of the channel selection member will display the running status of the A side. Even if the end position is reached and the tape end signal switches to B side running, the display of A side running status will be maintained unless the channel selection member is released from the recessed state by continuing to press the switch, resulting in an incorrect display. has.

Furthermore, according to the conventional configuration, an unnecessary load for operating the tape player is applied to the tuning member that requires the highest tuning accuracy, which reduces the tuning accuracy of the push-button tuner itself. There was a fear that it would be damaged.

Therefore, the present application solves such inconveniences, and examples thereof will be described in detail below with reference to the drawings.

Figures 1 to 7 show a pair of channel selection members arranged on the left and right positions of a single operating member developed by the applicant, and the pair of channel selection members are alternately moved forward and backward for each back and forth movement of the operating member. This is an example of a multi-band push-button tuner that is configured to be moved to select a station. 3a and 3b, a switching lever 5 whose intermediate portion is rotatably mounted on the upper surface via a pivot shaft 4, and a spring 6 that maintains the rotating state of the switching lever 5. support piece 7

and the main drive gear 11 and the front plate 13a of the support frame 13.
A spring 15 is provided between the push button 1 and the push button 1 for pressing the rear surface of the main gear 11 against a cut and raised piece 14 provided by cutting and raising from the bottom plate 13c of the support frame 13.
2 and the rear plate 13b of the support frame 13, return springs 16 of the operating member 1 are interposed, respectively. Further, the bottom plate 13c of the support frame 13 is formed with a guide hole 17 that engages with the engagement piece 3c extending from the lower end of the rear piece 3b of the support piece 7 and guides its back and forth movement.

A pair of channel selection members 1 forming a pair with the operating member 1
8 and 18' have the same configuration, and for convenience of explanation, the specific configuration of one channel selection member 18 is shown, and the other one is distinguished by adding ' in the drawings. That is, the channel selection member 18 consists of a long shaft rod 19, and the shaft rod 19 has a threaded portion 20, which is formed in a horizontal U-shape, and is axially arranged such that the front and rear pieces thereof are located in front and behind the threaded portion 20. A stopper piece 21 that is fixed and free in the rotational direction, a driven gear 22 that can mesh with the main drive gear 11 and has a larger diameter than the main drive gear 11, and a driven gear 22 that is screwed together with the threaded part 20 and has an abutment part 23 expanded on the upper surface. A protruding square block-shaped tuning piece 24 is provided, and the stopper piece 21 contacts the rear edge of one tongue piece 5a of the switching lever 5 to rotate the switching lever 5. and a locking piece 26 that comes into contact with the front edge of one tongue piece 5a of the switching lever 5 and causes the channel selection member 18 to move together when the operation member 1 moves forward. The channel selection members 18, 18' configured in this manner are rotatably and longitudinally movably supported on the front and rear plates 13a, 13b of the support frame 13 parallel to the left and right positions of the operating member 1, and the front plate 13a and the driven gears 22, 22', there are channel selection members 18, 1 that press the driven gears 22, 22' rearward, respectively.
8' return springs 27, 27' are interposed, and the bottom plate 13c of the support frame 13 is engaged with engagement pieces 28, 28' extending from the lower edges of the front pieces of the stopper pieces 21, 21'. Guide holes 29 and 29' are respectively provided for guiding the back and forth movement thereof.

As shown in FIG. 5, the relationship between the operation member 1 and the pair of channel selection members 18, 18' located on the left and right sides of the operating member 1 is such that the channel selection member 18' located on the right side is locked by a lock plate, which will be described later. The channel selection member 18 and the operating member 1, which are held in the forward movement state and are located on the left side, are in the return state by the return springs 27 and 16, respectively, and the switching lever 5 is further tilted to the left, and one tongue piece 5a is moved. When the front edge is in a state opposite to the protruding piece 25 of the stopper piece 21 provided on the left-side channel selection member 18, when the push button 12 is pressed from this state, the one tongue piece 5a and the stopper piece 21 are pressed. Through contact with the locking piece 26, the operating shaft 1 and the tuning member 18 located on the left side move forward together, and during this forward movement, as will be described later, the tuning member 18' located on the right side moves forward.
The forward motion holding state by the lock plate 31 is released,
It is returned by the return spring 16', and
The forward moving state of the channel selection member 18 in the forward left position is maintained by a lock plate 31, which will be described later, and the state shown in FIG. 6 is reached. Next, when the push button 12 is released, the operating member 1 is returned to its original position by its return spring 16, but during this return process, the rear edge of one tongue piece 5a of the switching lever 5 is attached to the channel selection member 18 located at the left side. The switching lever 5 is rotated clockwise in the figure by colliding with the projection 25 of the stopper piece 21, and this state is maintained by the spring 6 and the other tongue of the switching lever 5 is rotated as shown in FIG. Piece 5
The front edge of b is in a state where it can come into contact with the locking piece 26' of the stopper piece 21' provided on the other channel selection member 18'.

That is, each time the operating member 1 moves back and forth, the switching lever 5
are alternately switched, and the operating member 1 and the pair of left and right channel selection members 18, 18' are in a state in which they can relatively move together in the forward movement direction.

A pin 30a is provided at a front position of the support frame 13 so as to move laterally in the width direction on the surface of the bottom plate 13c.
A lock plate 31 is disposed through engagement with the lock plate 31, and this lock plate 31 is always urged in one direction in the longitudinal direction by a spring 32. This lock plate 31 is provided with stopper parts 21 to 2 of the tuning member when the tuning shaft moves forward together with the operating member 1.
The inclined edge 33a acts with the engaging pieces 28 to 28' provided at the terminal 1' to laterally move the lock plate 31 in a direction that resists the elasticity of the spring 32, and when the channel selection member moves forward sufficiently, An engagement stopper 33, which is formed by connecting the coupling pieces 28 to 28' and a engagement step 33b, is provided corresponding to each channel selection member. 34 is an escape hole of the cut and raised piece 14. Reference numeral 35 indicates the bottom plate 1 of the support frame 13 in parallel with the lock plate 31.
The operation plate 3c is provided on the operation plate 3c so as to be movable laterally through the engagement of the pin 36 and the elongated hole 37, and is always elastically biased in one direction by the spring 38. 1 has an inclined part 39a at its rear end that acts with the engagement piece 3c provided on the support piece 7 to move it laterally against the operating plate 35 and the spring 38 when it is moved forward. The slit 39 maintains the operating state while the operating member 1 moves back and forth one time.
are provided corresponding to each operating member 1, and include a switch 40 for stopping or reducing the receiving function of the receiving circuit, which is activated by the lateral movement of the operating plate 35, and an electromagnetic plunger to be described later. A switch 41 for energizing is provided at a suitable location on the support frame 13. Reference numeral 42 denotes a slide plate in which the variable element 43a of the variable tuning section 43 is supported on the front edge rib, and both ends are guided and supported by guide rods 44 which are fixed to the front and rear plates 13a and 13b of the support frame 13 so as to be movable back and forth. , At its center, there is a support rod 4 extending in the front and back direction.
5 is pivoted with a cut and raised piece 46. This support rod 4
5 is loosely inserted into the rear plate 13b of the support frame 13, and its front end forms a movable shaft of the electromagnetic plunger 47, which is inserted into the coil body of the electromagnetic plunger 47. This electromagnetic plunger 47 is embedded in a part of the variable tuning section 43,
Also, a spring 48 is interposed between the variable tuning section 43 and the slide plate 42, which always applies a backward elastic force to the slide plate 42. The electromagnetic plunger 47 is set to be weaker than the biasing force of the spring 48 which is activated when the switch 41 is closed and elastically biases the slide plate 42 rearward, and to act in a direction to reduce the biasing force.

When the push button 12 located at an arbitrary position is pressed, one of the tuning members 18 to 18' located on the left and right of the button moves forward together with the operating member 1, and the forward-moved tuning shaft moves toward the stopper part. The engagement pieces 28 to 28' of 21 to 21' are connected to the engagement slit 33.
When the lock plate 31 comes into contact with the inclined edge 33a of the lock plate 31 and engages with the engagement step 33b, the forward movement state is maintained, and the selection which was already held in the forward movement state is When the locking plate 31 is moved laterally, the forward movement holding state of the stationary member is released and the stationary member returns to its original state. When the push button 12 is released from this state, the operating member 1 also returns and the switching lever 5 is reversed and switched. On the other hand, when the push button 12 is pressed, the operation plate 35 moves laterally against the spring 38, the switch 40 is opened and the function of the receiving circuit is stopped, and when the switch 41 is closed, the electromagnetic plunger 47 is activated. If the electromagnetic plunger 47 is not provided, the slide plate 42 in pressure contact with the channel selection piece of one of the channel selection members held in the forward motion state is moved by pressing the push button 12 to At the same time, it moves backward by the spring 48 and collides with the tuning piece of the other tuning member which is moving forward together with the operating member 1. However, due to the action of the electromagnetic plunger 47, the spring Since the elastic force of 48 is reduced, the slide plate 42 slowly moves rearward and collides with the tuning piece of the other tuning member, which is moving forward together with the operating member 1, with a weak force. After the collision, the slide plate 42 moves forward together with the other tuning member, and the locking plate 31 holds the sliding plate 42 in its forward movement state, and the operating member 1 returns, and the operating plate 35 also returns. When the switch 41 becomes inactive, the action of the electromagnetic plunger 47 disappears.
Therefore, the slide plate 42 is then strongly pressed against the tuning piece of the tuning member held in the forward moving state by the elasticity of the spring 48. That is, due to the action of the electromagnetic plunger 47, the force of collision between the slide plate 42 and the selection piece during movement is reduced, and the pressing operation of the push button becomes easier.

However, any one of the channel selection members 18 to 1
8' is held in the forward movement state, and the other channel selection member and the operating member 1 are both returned to their original positions (the states shown in FIGS. 5 and 7), and when the push button 12 is rotated,
The tuning member is rotated by the meshing of the main gear 11 and the driven gears 22 to 22', and the tuning piece moves in the front and back direction, and the slide plate 42 follows accordingly, and the variable tuning section 43 is varied, and the tuning is changed. A point is captured. That is, a preset operation is performed. After the desired station is stored in the selection piece of each selection member in this way, by pressing any push button 12 to hold the desired selection member in the forward movement state, the selection member can be moved forward. The station stored in the selected station piece is selected. On the other hand, when the operation plate 35 moves laterally to the left in FIG. 4 due to the forward movement of the operation member 1, the switch 40, which had been in the ON state to normalize the reception function of the reception circuit, switches to OFF and receives the signal. The function is stopped or reduced, and this state is maintained while the operating member 1 makes one reciprocation in the front-rear direction. Therefore, the variable tuning section is changed to follow the noise mixed in when switching channels and the back-and-forth movement of the channel selection member. It is possible to avoid outputting unnecessary channel selection audio due to the movement of 43.

FIG. 8 shows the push-button tuner A described above in a tape player B shown in, for example, Japanese Patent Publication No. 55-20480.
It shows a schematic diagram of a composite device built into the
In the figure, 50 is a front display panel, which includes operating members 1, 1a, 1b, 1, as shown in FIG.
For example, at the positions corresponding to c, . "REW" to display rewind status
and lamps 51, 51a, 51b, 51c, and 51d are provided at each position. On the other hand, at positions facing the operation members 1, 1a, 1b, 1c, and 1d of the tape player B, there are an operation switch 52a for running the A side, an operation switch 52b for running the B side, an operation switch 52c for fast forwarding, and an operation switch 52c for rewinding. An operation switch is provided for each.

Although not shown, a switch for switching between the radio circuit and the tape play circuit is provided.

In a tape play operation, for example, when the operating member 1a is pressed, the shaft 2 moves forward to actuate the opposing operating switch 52a and then returns to its original position. Therefore, the tape player plays back the A side of the tape, and the display lamp 51a for playing back the A side.
lights up. In this state, when the tape reaches the end position and the tape is switched to B-side playback by the tape end signal, the B-side playback indicator lamp 52
b lights up. In this case, the A-side playback indicator lamp 5
Since the operating member 1a located at the position corresponding to 1a is in the restored state, there is no risk of erroneous display.

Therefore, according to the present application, each operation member of the push-button tuner can be used as the operation button of each operation switch of a tape player without any problem, and the load for operating the tape player is not placed on the channel selection member. Since it does not work, there is no risk of loss of channel selection accuracy, and there is no risk of erroneous display.
