Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The invention relates to a disc record player.
In particular, the present invention relates to a mechanism for regulating the vertical position of a pickup bracket during loading and ejecting operations of a disc record.

(Prior Art) In a slide-insertion type disc record player, a disc record is mounted on a spindle provided on a pickup bracket to perform record play. If this pick-up bracket is completely fixed to the device frame, vibrations of the vehicle will be directly transmitted to the pick-up bracket in in-vehicle equipment, creating a problem that it will be impossible to stably rotate the disc record. Therefore, in general, in car-mounted disc record players, the pick-up bracket is attached to the device board via a buffer means such as a spring, so that the pick-up bracket becomes independent from the vibrations of the vehicle, and the disc record can be played stably at all times. can be rotated.

In this manner, when the disc record is mounted on the spindle, it is desirable that the pick-up bracket is movable relative to the device frame.
In the reverse eject operation, if the position of the pick-up bracket is movable relative to the device frame, the loading or eject operation may be performed with the disc record tilted or vertically shifted relative to the device frame. As a result, the disc record may interfere with the device frame, causing problems such as inoperability or damage to the disc record.

Therefore, conventionally, in such a disc record player, the pick-up bracket is movable with respect to the device frame via a buffer means, and a regulated portion is provided in the pick-up bracket, so that the pick-up bracket can be moved during loading or ejecting operations. The pickup bracket is configured to be fixed in a fixed position relative to the device frame by locking this regulated portion.

Conventionally, as a mechanism for regulating the position of such a pick-up bracket, a pin is provided on the side surface of the pick-up bracket as a regulated part, and this pin is engaged with a regulating groove of a slide plate provided so as to be slidable. There are other configurations such as engaging with a rotatable hook.

However, in such a pick-up bracket position regulating mechanism, the pick-up bracket is movable at least in a direction opposite to the regulating direction of the pin.

Furthermore, in general, in-vehicle disc record players are required to be compact and simple, as the space for installing the device inside the vehicle is extremely limited. It is required to have a simple configuration with a small number of parts and to contribute to the miniaturization and simplification of the device.

(Problems to be solved by the invention) The present invention was proposed to solve the problems of the prior art as described above, and its purpose is to easily and reliably regulate the position of the pick-up bracket. To provide a position regulating mechanism for a pick-up bracket that is simple in structure and capable of controlling the position of a pick-up bracket without increasing the number of parts.

[Structure of the invention] (Means for solving the problem) The position regulating mechanism of the pick-up bracket according to the invention is provided with a regulated portion protruding from both sides of the pick-up bracket, and the regulated portion is fixed to the position during loading operation. It is inserted into the regulating part of a slide plate that reciprocates back and forth during the eject operation, and the regulated part inserted into the regulating part is pressed and fixed to the regulating side by a rotatable lock plate. It is. The slide plate is further provided with a lock plate pressing portion that presses the lock plate in the locking direction.

Furthermore, the regulating part of the slide plate has a horizontal regulating groove into which the regulated part of the pick-up bracket is inserted during loading and ejecting operations, and a regulating groove in which the regulated part of the pick-up bracket is released when the disc record is attached to the spindle. It consists of a relief part and an inclined part that guides the regulated part of the pick-up bracket from the relief part to the regulation groove at the start of ejection.

(Function) In the position regulating mechanism of the pick-up bracket of the present invention having the above-mentioned configuration, the regulated part inserted into the regulating part of the slide plate is pressed and fixed to the regulating side by the lock plate, so that The regulated portion is securely positioned by being sandwiched between the slide plate and the lock plate.

(Embodiment) An embodiment of the pick-up bracket position regulating mechanism according to the present invention as described above will be specifically described with reference to the drawings.

*Configuration of the Embodiment* In FIGS. 1 and 2, reference numeral 1 denotes a horizontal plate-shaped regulated portion provided protruding from the side surface of the pick-up bracket.

A slide plate 3 is provided inside the side plate of the device frame 2. This slide plate 3
When loading disk record 4,
That is, when moving backward from the insertion position at the front of the device (left side in the figure) to the operating position at the rear of the device (right side in the figure), it moves in the same direction, and when the disc record 4 is ejected, that is, when moving forward from the operating position to the insertion position. When moving, they move in the same direction.

In addition, the slide plate 3 includes the same plate 3.
a horizontal regulating groove 5 into which the regulated portion 1 of the pick-up bracket is inserted from the front when the plate 3 is at the front of the device; and a relief portion 6 that releases the regulated portion 1 of the pick-up bracket when the plate 3 is at the rear of the device. and a V-shaped inclined portion 7 that guides the restricted portion 1 of the pick-up bracket from the escape portion to the restriction groove when the plate 3 moves forward.

On the other hand, in front of the regulated portion 1 of the pick-up bracket on the side plate 2 of the device frame, a lock plate 9 for pressing and fixing the regulated portion 1 rearward is provided so as to be rotatable in the front-rear direction. This lock plate 9 is urged forward, which is the non-locking side, by the urging force of a spring 10, and when the slide plate 3 is located at the front of the device and the regulated portion 1 of the pick-up bracket is inserted into its regulation groove 5. At this time, it is pressed by the lock plate pressing part 11 provided on the slide plate 3 and rotates backward,
The regulated portion 1 is pressed and fixed within the regulation groove 5. Here, the lock plate pressing part 11
is a horizontally elongated protruding plate located above the regulating portion 8 of the slide plate 3.

Further, as shown in FIGS. 3 and 4, the pick-up bracket 12 is attached to the device frame 2 via cushioning rubber 13 using pins 12a provided at four locations. Furthermore, in FIGS. 3 and 4, reference numeral 14 is an upper guide provided above the pick-up bracket 12 so as to be rotatable in the vertical direction with respect to the pick-up bracket 12; A holding member 15 is attached for pressing the disc record from above and mounting it onto the spindle of the pick-up bracket 12.

FIG. 2 shows the position regulation state of the pick-up bracket when the disk record 4 has been ejected completely, that is, the disc record is in the insertion position. , until the loading operation is performed, that is, while the slide plate 3 is in front.
Further, FIG. 4 is a plan view corresponding to FIG. 2.

Therefore, even if the regulated part of the pick-up bracket is regulated, the regulated part is movable to the non-regulated side in the present embodiment, compared to the conventional technology, in which the regulated part 1 of the pick-up bracket is moved to the slide plate 3. and the lock plate 9, and are securely positioned. By the way, if the regulated part is pin-shaped, there is a risk that the regulated part may rotate within the regulation groove, but in this embodiment, the regulated part 1 of the pick-up bracket is in the form of a horizontal plate. The regulated portion 1 does not rotate within the regulation groove 5. That is,
In this embodiment, during loading and ejecting operations, the pick-up bracket can be held in a fixed position without tilting in the front-rear direction, so that misalignment between the device frame and the pick-up bracket will not interfere with the operation of the disc record. By reliably preventing problems such as causing damage to the disc record or causing damage to the disc record, smooth loading and ejecting operations can be performed.

Furthermore, the configuration of this embodiment is simple and has a small number of parts, consisting of only the restricted part 1 of the pick-up bracket, the slide plate 3 having the restricting part 8, and the lock plate 9, and therefore is suitable for application to in-vehicle equipment. It also has the advantage of being excellent.
