Abstract

PURPOSE:To use a panel as a push button, by providing L-shaped projected sections at the upper and lower edges of the front face of a tray, a panel equipped with L-shaped projected sections which are slidably engaged with the L-shaped projected sections of the tray, and a switch between the tray and panel. CONSTITUTION:Under normal conditions, a panel 2 is pushed forward by means of the returning force of a switch 4 and the L-shaped projected sections 10 and 11 at the upper and lower edges of the panel 2 and the L-shaped projected sections 3 and 9 provided at the upper and lower edges of a parts 1b contact. When the lower surface of the panel 2 indicated by the arrow B is pushed under this condition, the L-shaped projected section 10 at the upper edge of the panel 2 contacts the upper L-shaped projected section 8 of the parts 1b and the panel 2 rotates around the contacting position and turns on the switch 4. When the upper face of the panel 2 indicated by arrow A is pushed, on the contrary, the lower projected section 11 of the panel 2 contacts the lower projected section 9 of the parts 1b and the panel 2 rotates around the contacting position and turns on the switch 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette 7) for horizontally moving a tape cassette or a disk and mounting it at a predetermined position in a magnetic recording/reproducing apparatus, and a disk loading device.

2. Description of the Related Art A conventional cassette and disk loading device is as shown in FIG. 6, for example.

That is, a panel 2 is fixed to a tray 1 made up of parts 1&, 1b, and 10, a tape cassette 6 is placed on this tray 1, and the tray 1 is moved horizontally to the deck 6.
It is installed on the

At this time, loading is started using the push button switch 3 installed inside the panel 1. Alternatively, this is done by turning on a push button switch attached to the panel 6 of the deck.

Problems to be Solved by the Invention However, in such a structure, as the deck 6 is becoming smaller, the number of operation switches 7 is increasing and the number of operation functions is increasing, it is difficult to arrange them in a limited space. The size of the switch group 7 is becoming smaller and smaller, and the distance between adjacent switches is almost disappearing.

Therefore, when operating the tray start switch 4, etc., it is difficult to touch the adjacent switch group γ, and since the switches are small, it is difficult to operate them. On the other hand, there is also a device in which a loading start switch 3 is arranged on the panel 2, but this requires parts for the push button, which increases the cost.

SUMMARY OF THE INVENTION The present invention provides a cassette and disk loading device that has the same number of switches, improves operability so that adjacent switches are not touched when operating a loading start switch, and provides an inexpensive switch operating mechanism.

A means for solving the problem and a technical means for solving the above problem is to provide a tray with L-shaped protrusions on the upper and lower sides of the panel and L-shaped protrusions that slidably engage with the above-mentioned shapes. A switch is placed between the panel and the panel.

Effect The effect of this technical means is as follows. That is, the panel on the front surface of the tray is also used as a push button, and the operation can be performed by pressing any position on the panel surface.

As a result, there is no need to attach a loading start switch to the deck panel, the limited deck panel space can be used effectively, and the switch has an inexpensive switch structure with good operability.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 shown in FIG. 3 is a tray assembled into a concave shape from the parts 1a, 1b, and 10, which holds the tape cassette 6 and moves horizontally.

Further, the tray 1 has a panel 2 on the front side.

The inner surface of the panel 2 has an L-shaped protrusion 1o at the upper part shown in FIG. 1, and is attached to the L-shaped protrusion 8 of the component 1b so as to be slidable back and forth. It also has a rice cake-shaped protrusion 11 at its lower part and is attached to the L-shaped protrusion 9 of the component 1b so as to be slidable back and forth.

Further, 4 is a switch for loading start and unloading, which is arranged and attached at the center between the component 1b and the panel 2, and the panel 2 is urged forward by the return force of this switch 4. Normally, it is in the state shown in Figure 1.

Next, the operation of the configuration of this embodiment will be explained.

First, in a normal state, the panel 2 is urged forward by the return force of the switch 4, and the L-shaped protrusions 10, 11 on the top and bottom of the panel 2 and the L-shaped protrusions 8, 9 on the top and bottom of the component 1b. are in contact with each other, resulting in the state shown in Figure 1.

In this state, as shown in Fig. 2, when the lower part of the panel 2 is pressed against the arrow part B, the L-shaped protrusion 10 on the upper part of the panel 2 and the L-shaped protrusion 8 on the upper part of the component 1b come into contact, and the center is centered at that position. The panel 2 rotates and the switch 4 is turned on.

On the other hand, when the upper part of the panel 2 shown in FIG. and turn on switch 4 (not shown).

Also, if you press the right side C arrow part of the panel 2 shown in Fig. 3,
L-shaped protrusions 10°11 on the upper and lower left side of panel 2 and component 1
The upper and lower L-shaped protrusions 8 and 9 on the left side of b come into contact with each other, and the panel 2 rotates around that position, turning on the switch 4.

Conversely, when the left arrow part of the panel 2 is pressed, the L-shaped protrusions 10.11 on the upper and lower right sides of the panel 2 come into contact with the L-shaped protrusions 8 and 9 on the upper and lower left sides of the component 1b.

The panel 2 rotates around that position and the switch 4 is turned on (not shown).

As a result, the switch 4 can be turned on even if the panel 2 is pressed at any position.

Although the fifth embodiment of the present invention has L-shaped protrusions that engage at the top and bottom, a structure in which L-shaped protrusions are provided on the left and right sides will also have the same effect.

Effects of the Invention The present invention provides a panel having an L-shaped protrusion on the upper and lower sides of the front surface of the tray and an L-shaped protrusion that slidably engages with the above-mentioned protrusion, and a switch between the tray and the panel. As a result, the cassette loading device has a switch structure that is easy to operate and inexpensive because it can serve as both a panel and a push button.

Moreover, it also has the following effects.

That is, the present invention has the effect of eliminating the fear of touching other switches arranged on the deck panel by using the rotating start switch arranged on the deck panel also as the tray panel.
