Description

[Detailed explanation of the invention] a. Industrial application fields: Recording and/or recording of VTRs, CDs, other optical discs, etc.
Or regarding a playback device, in a recording/playback device equipped with a movable chassis that moves inside the main body of the recording/playback device when a recording medium is inserted into the main body, this recording/playback device is particularly effective for preventing accidents caused by people's fingers getting caught. Regarding a playback device.

b. Prior Art Many VTRs, optical discs, and the like are equipped with a mechanism (movable chassis mechanism) in which the movable chassis carrying a recording medium enters the inside of the device body when the recording medium is inserted.

However, although the movable chassis mechanism is easy to handle and has a good design sense, it has the problem that when a recording medium is inserted, a finger may get caught between the lid body that closes the insertion opening and the main body of the apparatus.

As a countermeasure to this problem, in many cases, for example, a separate operation button is provided so that operations can be performed by touching the operation button with a finger, that is, without touching the movable chassis or the lid.

There is also an example in which the lid is made as thick as the length of a fingertip to prevent the fingertip from entering the main body of the device.

Furthermore, the torque of the motor that drives the movable chassis is set to the minimum necessary so that if an obstacle such as a finger gets caught, the motor will idle and prevent the movable chassis from moving further. There are also examples.

c. Problems that the invention aims to solve However, in cases where weight and size are limited, such as portable VTRs, or where cost constraints are severe, problems such as loading and unloading tapes onto a head drum, and setting up an optical pickup are difficult to solve. Although the resetting and the like are automatic, it is not uncommon for the recording medium to be pushed forward by a person's hand or finger.

In the case of this method, a force such as a spring is usually applied, which often causes the problem of fingers being pinched.

Furthermore, even if the device implements the countermeasures described in the section b) of the prior art, it is still possible for an infant's finger to be caught in an accident.

The present invention proposes a simple and inexpensive means that is effective in preventing these finger pinch accidents.

d.Means for solving the problem In the present invention, the lid attached to the movable chassis is elastically supported and attached to the lid mounting portion of the movable chassis using a spring or the like. It has been resolved.

e. Effect As a result, even if a finger is caught, elastic play is generated between the lid and the main body of the device, so that the finger will not be injured. Moreover, the trapped finger can be easily pulled out.

In other words, this has been achieved by changing the idea from focusing on preventing fingers from becoming pinched, to preventing injury even if a finger should become pinched.

f Embodiment FIG. 1 is a conceptual diagram showing an example of implementation, in which FIG. 1 a shows the movable chassis in the open and closed state, FIG. 1 b shows the lid in the closed state in normal conditions, and FIG. Indicates a partially closed state of the body.

Fig. 2 is a conceptual diagram showing another embodiment, and Fig. 2a
2b shows a state in which the movable chassis is open (closed), FIG. 2b shows a state in which the lid is closed during normal operation, and FIG. 2c shows a state in which the lid is partially closed in an abnormal state.

FIG. 3 shows an embodiment of means for elastically supporting the lid on the movable chassis of FIG. 1 or 2. FIG.

FIG. 3a shows a movable chassis-integrated lid made of elastic material. The material includes synthetic rubber such as urethane,
Or you can use plastic. FIG. 3b shows an example in which the movable chassis portion 2 and the lid body 3 are elastically supported by a plate spring 4, and a plate spring fixing screw 5 connects the movable chassis portion 2 and the lid body 3. The leaf spring 4 has elasticity so that it can be closed to the device main body 1 without any gap in the normally closed state of the lid. FIG. 3c shows an example in which the lid is elastically supported by a coil spring 6, and a hinge 7 allows the lid to be half-opened outward.

The force of the springs shown in FIGS. 3b and 3c is selected to be about 1 kg, for example, to provide elasticity to the lid. This allows the lid to open and close normally, but if your finger gets caught, the spring stretches and an elastic play angle is created.

g. Effect of the invention By carrying out the invention, the lid body is elastically supported with respect to the lid attachment part of the movable chassis, so that in the unlikely event that a finger touches the end of the storage medium insertion opening of the device body, Even if the finger is caught between the finger and the lid, the lid is half closed, injury to the finger can be avoided, and the finger can be easily removed. Such a safe recording/reproducing device could be realized without any particular increase in production costs.
