Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a VTR with a timer.

[Outline of device]

In this invention, when the timer reservation door is opened, the timer setting key appears, and the timer reservation door is broken by setting the mode changeover switch and the timer reservation door in a predetermined interlocking relationship in the VTR in the timer setting mode. In some cases, the VTR is set to the normal mode.

[Conventional technology]

A home VTR is generally provided with a timer, and if this timer is set, a desired television program can be automatically recorded.

In such a VTR, when the timer reservation door is opened, various keys for setting the timer appear, and a VTR that is set to the timer setting mode is considered.

2 and 3 show a front view and a cross-sectional view of the timer reservation part of such a VTR, FIG. A showing a state in which the timer reservation door is closed, and FIG.

Further, (1) shows a display portion, which is constituted by, for example, a fluorescent display tube and is provided so as to face the upper half of the front panel of the VTR. The display unit (1) digitally displays the current time, the current reception channel, the timer recording start time when the timer is set, the recording channel, and the like. The figure shows a state where all the display elements of the display unit (1) are lit.

Further, (2) shows a timer reserved door, which is made of a plastic material in a rectangular shape having a long side in the left-right direction, is provided below the display section (1), and a lower part of its rear surface penetrates the pin. Supported by (3). Therefore, the door (2) can be opened and closed in the front-rear direction about the pin (3).

Further, (4) shows a timer setting key for setting the start time of timer recording, a recording channel, etc. These keys (4) are attached to the board (5), and when the door (2) is opened. It is provided in the opening. Also the substrate (5)
Is equipped with a micro switch (6) as a mode switch, and its actuator (6A) faces the upper rear surface of the door (2), and the switch (6) is turned on and opened when the door (2) is closed. It is sometimes turned off. Incidentally, (7) is a mode key for controlling the VTR to a reproduction mode, a recording mode or the like.

FIG. 4 shows a circuit related to timer reservation. That is, (11) represents a microcomputer for managing timer reservation, to which the display unit (1) is connected, and the timer setting key (4) and the switch (6) are connected. Also,
(12) shows a clock circuit for outputting the data of the current time, (13) shows a memory for storing data necessary for timer recording, and these are also connected to the microcomputer (11).

Further, (20) indicates a system controller for controlling the operation of the VTR, which is also constituted by a microcomputer and is used to access necessary data with the microcomputer (11).

When the reservation door (2) is closed (Fig. 2A,
3A), the switch (6) is pushed by the reservation door (2) to turn it on, but this is detected by the microcomputer (11) and the normal mode is determined.
It is supplied to (20) and the VTR is in normal mode. Therefore, pressing the mode key (7) will
0) controls the VTR to the corresponding operation mode.

When the reserved door (2) is open (Figs. 2B and 3B), the reserved door (2) does not press the switch (6), and the switch (6A) returns to the switch (6A). 6) is off, but this is detected by the microcomputer (11) and V
TR is in the timer setting mode. Then, in this timer setting mode, the state of accepting the input of the timer recording start time, end time, channel, etc. by the key (4) is entered, and when these are input, the data is stored in the memory (13).
When the "reserved recording" key of the key (4) is pressed at the end, the reservation is completed. Then, when the reservation door (2) is closed, the data indicating that the "reservation recording" key has been pressed and the switch (6) are turned on.
R goes into reserved mode.

Then, when the timer recording start time reserved with the key (4) is reached, this start time data and the clock circuit (12)
Coincides with the time indicated by, the microcomputer 11 detects this and the detection output is supplied to the syscon 20 so that the VTR enters the timer reservation recording mode and the target program is timer-recorded.

Thus, according to this VTR, since the timer reservation mode is entered only when the timer reservation door (2) is opened, and the key (4) necessary for timer reservation appears, the operation is simple and erroneous operations can be reduced and the operability is reduced. Is improved. Further, since the timer setting key (4) which is less frequently used is hidden by the reservation door (2) during normal use, there is no erroneous operation from this point.

Document: Specification and Drawings of Japanese Utility Model Application No. 60-200900 [Problems to be Solved by the Invention] However, in the case of the above-mentioned configuration, the reservation door (2) is provided as shown in FIG. 3B. If the reserved door (2) is accidentally pushed downward in the open state, the reserved door (2) may be broken before the pin (3) as shown by a broken line.

And when the reservation door (2) is broken like this, the switch (6)
Remains off due to the restoring force of the actuator (6A), the VTR remains in the timer setting mode, and recording by timer reservation as well as normal reproduction and recording cannot be performed at all.

The present invention seeks to solve such a problem.

[Means for solving problems]

Therefore, in this invention, the switch (6) is provided so that the reservation door (2) does not act on the switch (6) when the reservation door (2) is broken.

[Action]

If the reservation door (2) is broken, the VTR goes into normal mode.

〔Example〕

1A and 1B show sectional views corresponding to FIGS. 3A and 3B.
The reserved door (2) is integrally formed with a drive piece (2A) on the side opposite to the door side around the pin (3). Also,
In the switch (6), its actuator (6A) is the driving piece (2A).
It is provided at a position opposed to, for example, when the door (2) is closed, it is turned off, and when it is opened, it is turned on. Furthermore, in the microcomputer (11), the processing when the switch (6) is on and the processing when it is off are reversed from the above.

According to such a configuration, when the reserved door (2) is closed (Fig. 1A), the drive piece (2A) is separated from the actuator (6A) of the switch (6), so that the switch ( 6) is turned off by the restoring force of the actuator 6A, so that the VTR is set to the normal mode, and when the mode key 7 is pressed, it is controlled to the corresponding operation mode.

However, when the reserved door (2) is opened, the drive piece (2A) pushes the actuator (6A), so that the switch (6) is turned on, and thus the VTR is in the timer setting mode. Then, in this timer setting mode, if the key (4) is input and the door (2) is closed, the VTR becomes the reserved mode as described above,
The target program is timer-recorded.

On the other hand, if the reserved door (2) is accidentally broken, most of the door (2) will be removed.At this time, even if the drive piece (2A) remains, the actuator (6A) of the switch (6) ), The drive piece (2A) is rotated, the switch (6) is turned off, and the VTR is in the normal mode. Therefore,
If the reservation door (2) is accidentally broken, timer recording cannot be performed by timer reservation, but normal playback and recording can be performed.

Thus, according to this invention, when the timer reserved door (2) is broken, the mode changeover switch (6) is returned to the normal mode by the restoring force of the actuator (6A).
Since the reservation door (2) and the switch (6) are interlocked, even if the reservation door (2) is broken, normal reproduction and recording can be performed without any trouble.

In the above description, the on / off relationship of the switch (6) may be reversed. Further, the driving piece (2A) may control the actuator (6A) via another member.

[Effect of device]

According to this invention, when the timer reservation door (2) is broken, the mode changeover switch (6) causes the actuator (6A) to move.
Reserved door to return to normal mode by the return force of
Since the (2) and the switch (6) are linked, the reserved door (2)
Even if is broken, normal playback and recording can be performed without any problems.

[Brief description of drawings]

FIG. 1 is a sectional view of an example of the present invention, and FIGS. 2 to 4 are diagrams for explaining the same. (2) is a timer reservation door, (4) is a timer setting key, and (6) is a mode switch.
