Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording apparatus capable of recording an image, and more particularly to an image recording apparatus having a jog shuttle operation and a cursor selection operation.

[0002]

2. Description of the Related Art Some video recording apparatuses capable of recording video are equipped with a jog shuttle dial for controlling a playback speed such as fast forward search or rewind search, frame advance or slow playback of video. Some products are provided with a cursor switch used for selecting menu operations and selecting thumbnail images. These jog shuttle dials and cursor switches
The device must be located in an easy-to-operate location on the front or surface of the device.

In the input device disclosed in Japanese Patent Application Laid-Open No. 10-199124, a jog shuttle portion and a cursor portion are provided integrally to prevent the device from being enlarged and to improve operability.

FIGS. 7 and 8 show an example of a layout of a conventional jog shuttle section and a cursor section.

As shown in FIG.
1, and the jog shuttle dial 72 is arranged around the position. The cursor switch 71 is tilted in the directions of the up, down, left, and right marks, so that the shaft 81 at the center is tilted, and the up, down, left, and right direction instruction input operations are performed at the cursor switch contact section 82. Jog shuttle dial 72
Is provided on the periphery of the cursor switch 71, and rotates clockwise or counterclockwise with the concave portion 73 of the dial as a power point, so that the contact piece 8 of the jog shuttle dial 73 is rotated.
A rotation signal input operation is performed by a rotation signal obtained by sliding between the fourth member 4 and the fixed portion 83.

[0006]

However, since both the jog shuttle dial and the cursor switch are separate input operations, there is a limit to arranging the switches integrally and compactly without impairing the operability. Since the cursor switch is operated by tilting the key top of the switch, operability deteriorates if the tilt amount of the switch is impaired with priority given to miniaturization. Further, since the jog shuttle dial is arranged around the cursor switch, it is impossible to make the jog shuttle dial smaller than the cursor switch. In the case of a device that requires further miniaturization, it is difficult to arrange them integrally, and it is necessary to arrange them as separate switches and dials.

In the above-mentioned prior art, the jog shuttle dial is arranged around the cursor switch. However, each is a separate input operation, and there is a limit in reducing the size without impairing the operability.

The present invention has been devised in order to solve the above-mentioned problem, and enables a rotary input operation such as a jog shuttle dial and a direction instruction input operation such as a cursor switch to be performed using the same input operation switch. And the size can be reduced without impairing the operability.

[0009]

According to the present invention, in order to solve the above-mentioned problems, instead of the conventional four-direction cursor switch section, a large number of eight, twelve or sixteen as shown in FIG. Are arranged in a circle along the outer periphery of the cursor switch. Use the four switches up, down, left, and right as a cursor switch, and use the many switches as a jog shuttle dial. By pressing the key tops along the outer circumference, the switches next to each other are continuously It is configured such that an input signal similar to a conventional rotation input signal can be obtained by being pressed. With this configuration, a small input operation mechanism can be realized without impairing the operability.

Is an apparatus video display unit, and 15A to 15L are input switches.

FIG. 2 is a layout diagram of an input operation unit according to the present invention, wherein 21 is a key top of an input switch, 22 is a fulcrum,
23 is a key arm.

FIG. 3 is a top view, AA sectional view, and BB sectional view of the input operation unit according to the present invention. Reference numeral 31 denotes a groove on the outer peripheral portion.

FIG. 4 is a state diagram at the time of a direction indicating operation of the input operation unit according to the present invention. Reference numeral 41 denotes a finger.

FIG. 5 is a state diagram at the time of a rotation input operation of the input operation unit according to the present invention.

FIG. 6 shows waveforms obtained from the respective input switches when the rotary operation of the input operation unit according to the present invention is performed.

As shown in FIG. 2, the key top 21 has a key arm 23 on the outer periphery. Key top 21 is fulcrum 22
Is configured to fall in the outer peripheral direction around the axis. Each of the input switches 15A to 15L is arranged at a position where the key arm 23 is lowered and pressed by the key top 21 falling down. Outputs of the input switches 15A to 15L are input to the switch detection unit 11. The switch detection unit 11 grasps the state of each of the input switches 15A to 15L and sends the information to the device control unit 12. Device control unit 12
Processes the information of the switch detection unit 11 and controls the device video processing unit 13 to display necessary information on the device video display unit 14.

When performing a direction instruction input operation as a cursor switch such as menu operation or selection of a thumbnail image,
As shown in FIG. 3, when performing an input operation in the vertical direction, A
Fold the key top 21 in the direction of the mark in the -A direction. When performing an input operation in the left-right direction, the key top 21 is tilted in the direction of the mark in the BB direction. For example, when performing a rightward input operation, as shown in FIG. 4, when the key top 21 is tilted rightward with the finger 41, the key arm 23 is pivoted about the fulcrum 22.
And the input switch 15A is pressed. In the same manner, input information in the up, down, left, and right directions can be obtained. At this time, the up, down, left, and right input switches 15A, 15D, 15G,
If a method other than 15J is set so that input is prohibited, malfunction can be suppressed. Also, when using the cursor switch to select any part of the screen,
By making use of all the input switches, it is also possible to make a diagonal movement or the like.

When performing a rotation input operation of a jog shuttle function for performing a fast-forward search, a rewind search, a frame-forward function, and the like of a video, in addition to the same operation as the above-described direction instruction input operation, as shown in FIG. By pressing the switch with a finger 41 and further moving the finger 41 along a groove 31 provided on the outer periphery of the key top 21, the inclination of the key top 21 changes, and the input switch 1 already pressed is changed.
The input switch 15B next to 5A is pressed. And finger 4
By moving 1, the input switches 15C and 15D are continuously pressed. At this time, the input switch 15A is configured to be released before the input switch 15C is pressed. The switch group configured in this way outputs a waveform as shown in FIG. The output waveform changes the time during which each of the switches 15A to 15L is on and the time from when one switch is turned on until the next switch is turned on, depending on the speed at which the finger 41 moves. Thereby, the rotation speed can also be detected. Further, by reversing the moving direction of the finger 41, the output waveform is reversed. The switch detection unit 11
A rotation direction, a rotation amount, a rotation speed, and the like are detected from output waveforms of the input switches 15A to 15L, the information is processed, and an input operation intended by the user is sent to the device control unit 12 to operate the device.

With this configuration, the direction input operation of the cursor switch and the like and the rotation input operation of the jog shuttle dial and the like can be realized using the same input operation switch, and the size can be reduced without impairing the operability. become able to.
