The input unit 109, the disk control unit 110, and the display control unit 111 are included.

The tilt measuring unit 101 detects a rotation mechanism and a gimbal mechanism that rotate in the direction of gravity, a weight supported by these two mechanisms, and a weight that floats in the direction of gravity, and the rotation of the above two mechanisms. It is an omnidirectional tilter having two servo type angle sensors, and the measured values of the two servo type angle sensors give the above angles ω1 and ω2. The installation position of the inclination measuring unit 101 is determined inside the main body so that the above two mechanisms are parallel to the short side L1 and the long side L2 of the main body.
The configuration of the inclination measuring unit 101 is disclosed in Japanese Patent Laid-Open No. 63-639.
13, the detailed description thereof will be omitted. Note that the tilt measuring unit 101 may be any other measuring device as long as it can measure the tilt of the main body.

The sampling unit 102 includes a timer and an A / D.
Of the angles detected by the tilt measuring unit 101, which is provided with a converter, the angle formed by the short side of the main body with the horizontal plane, ie, the angle ω1
Is A / D converted at regular intervals. Sampling unit 10
An example of the result of sampling by 2 is shown in FIG. In the figure, t, t + 1, t + 2, t + 3, t + 4 ... Indicate the time at which sampling is performed, and 0 °, + 5 °, −8.
.Degree., +35, ... Show the angle after A / D conversion.

In the state symbol table 103, the range in which the body can be tilted is divided into a predetermined number and the symbols given meaning to the respective divisions are described in association with each other. Each section of the above range is called an angle range, and the above symbols are called state symbols. An example of the status symbol table 103 is shown in FIG. The range of angles in this figure is “−180 ° <ω ≦ −60
° "," -60 ° <ω ≤ -30 ° "," -30 ° <ω ≤
“+ 30 °”, “+ 30 ° <ω ≦ + 60 °”, “+ 60 °
<Ω ≦ + 180 ° ”is each of the above categories. Further, the state symbols "A" and "E" in the figure indicate that the main body is greatly inclined in the positive and negative directions, and the state symbols "B" and "D" indicate that the main body is slightly inclined. Further, the state symbol “C” indicates that the inclination of the main body is regarded as invalid.

The reading unit 104 searches the state symbol table 103 for an angle range in which the A / D converted angle is within the range, and reads the state symbol corresponding to the angle range. The thinning writing unit 105 includes a control unit, and writes the status symbol read by the reading unit 104 into the status symbol buffer 106. It should be noted that this writing is performed after confirming that the state symbol to be written is different from the one previously written. Thinning writing unit 1
The control flow chart of 05 is shown in FIG. The thinning writing unit 105 is activated by the reading unit 104 when the reading unit 104 reads the status symbol. The thinning writing unit 105 inputs the state symbol read by the reading unit 104 (step s1) and checks whether the input state symbol is the same as the previously written state symbol (step s2). If they are the same, the processing is terminated, and if they are different, the input status symbol is written in the status symbol buffer 106 (step s3).

In the status symbol buffer 106, the status symbols written by the thinning writing section 105 are stored in the order of writing. In the operation item table 107, the state symbol string and the operation command are described in association with each other. The state symbol string represents the transition of the state when the main body is tilted by the sequence of state symbols,
The operation command is a command having the same function as the control command generated by the input unit 109 when the operation is performed. FIG. 6A shows an example of the operation item table 107 when the counterclockwise inclination of the short side of the main body is set in the direction of increasing the number of pages and decreasing in the clockwise direction. "B → A" in the figure
→ B ”,“ B ”,“ D ”,“ D → E → D ”are status symbol strings, and“ previous chapter ”,“ previous page ”,“ next page ”, and“ next chapter ”in the figure indicate these. Is an operation command corresponding to the state symbol string of. Operation command corresponding to "B → A → B""Previouschapter"
Is for paging the electronic book up to the previous chapter. The operation command "previous page" is for the previous page, "next page" is for the next page, and "next chapter" is for the next chapter. .

The operation item reading unit 108 includes a control unit, reads a state symbol string from a series of state symbols stored in the state symbol buffer 106, searches the operation item table 107 with the read state symbol string, Reads and outputs the corresponding operation command. FIG. 7 shows a control flowchart of the operation item reading unit 108. In this figure, the position i is described as an index position for the operation item reading unit 108 to refer to the state symbol buffer 106, and the state symbol string is described as a state symbol string is generated. Is the internal buffer of.

When the start command issued from the disk control unit 110 is input, the operation item reading unit 108 moves the i position to the head of the status symbol buffer 106 (step s11), and the status symbol indicating that the i position is invalid. Is checked (step s12). If it is valid, the i position is incremented until the i position becomes an invalid status symbol (step s13). If it is invalid, the status symbol string is cleared (step s14). After clearing, it is determined whether or not there is a status symbol at the i position, and if there is, it is determined whether or not the status symbol is a status symbol indicating a valid state (step s15, step s16). If it is valid, the state symbol at the i position is added to the state symbol string buffer, and after the addition, the i position is incremented (step s
17, step s18), and the same processing is repeated for the next status symbol string buffer. In the above determination, if the state symbol at the i position indicates invalidity (step s1
6) The operation item table 107 is searched for the status symbol string generated by the processing up to that point (step s19), and if a matching status symbol string exists, the corresponding operation command is read and output to the disk control unit 110. (Step s2
0), i position is incremented (step s2
1). If it does not exist, only the i position is incremented (step s21). The i position is incremented one after another, and when the i position reaches the end of the state symbol buffer 106 (step s15), the state symbol buffer 106
Is cleared and the process ends (step s22).

The input unit 109 is provided with an operation switch, and when the operator operates, it outputs a control command according to the operation to the disk control unit 110. Disk controller 110
Controls access to the optical disc. Display control unit 11
The display control unit 1 controls the display of the display screen (LCD) of the electronic book player 100 according to the control of the disc control unit 110.

As described above, according to the present embodiment, it is possible to perform preset operations such as page turning and channel operation according to the angle by tilting the main body without operating the button. Moreover, since the angle is used, an intuitively understandable operation means is realized. Although the inclination is the rotation angle of the short side in the present embodiment, the rotation angle of the long side may be the inclination.

If the main body is a liquid crystal television, the operation item table 107 may correspond to the contents peculiar to the television. An example is shown in FIG. “Volume increase” and “volume decrease” in the figure change the volume of the liquid crystal television, and “channel number increase” and “channel number decrease” change the number of channels. (Second Embodiment) In the first embodiment, one operation is performed by inclining the main body to a predetermined angle and then returning it, but in the second embodiment, one operation is performed by simply inclining the main body. It is designed so that you can In order to enable such an operation, the operation item table has a one-to-one correspondence between status symbols and operation items as shown in FIG. As shown in the figure, the operation symbol "previous chapter" is associated with the status symbol "A". Similarly, the status code “B” is associated with “previous page”, the status code “C” is associated with “next page”, and the status code “D” is associated with “next chapter”. As described above, since each status symbol corresponds to the operation item, all the writing of the writing unit (not shown) in the second embodiment is performed without thinning out the status symbol read by the reading unit. The data is written in a buffer (not shown). The status symbols thus written are read one by one by the operation item reading unit (not shown) and used for searching the operation item table. The operation command corresponding to each status symbol is read by the search.
Output for disk control.

According to the electronic book player of the second embodiment as described above, when the main body is kept tilted, a command corresponding to the angle is automatically issued. The operation is performed automatically. (Third Embodiment) In the third embodiment, when the long side of the main body is tilted so that the display screen cannot be seen, the processing is not performed. Therefore, the electronic book player 300 of the third embodiment includes a vertical state determination unit 303 and a switching unit 304 in addition to the configuration of the electronic book player 100 as shown in FIG. In addition, the sampling unit 102
Instead of the above, a first sampling unit 301 and a second sampling unit 302 are provided.

The first sampling section 301 has the name of the sampling section 102 changed for convenience of explanation. The second sampling section 302 has exactly the same configuration as the first sampling section 301. However, the second sampling unit 302 does not A / D-convert the angle ω1 but A / D-converts the angle ω2 formed by the long side of the main body and the horizontal plane at regular intervals.

The vertical state determining unit 303 determines whether the angle A / D converted by the second sampling unit 302 is within a predetermined range. In the present embodiment, the above predetermined range is set to + 90 ° or more and −90 ° or less. The switching unit 304 sets the measurement value of the first sampling unit 301 read by the reading unit 104 only when the vertical state determination unit 303 determines the predetermined range,
Switch to a predetermined angle. The predetermined angle in this embodiment is set to 0 °.

As can be seen from the above, according to the third embodiment, when the state symbol "B → A" has already been stored in the state symbol buffer 106, it is detected that the main body long side is intentionally tilted. The inclination of the main body is switched to 0 °. Since the state symbol table 103 is searched at 0 °, the reading unit 104 reads out the state symbol indicating the invalid state. The read status symbol is stored in the status symbol buffer 106. By this storage, the status symbol buffer 106 is stored.
The series of status symbols in the meanings of the status symbols become meaningless. Therefore, the corresponding operation command is not read from the operation item table 107, and the electronic book player is not operated. (Fourth Embodiment) In the fourth embodiment, considering that the operation direction is opposite between the case where the hand holding the main body is the right hand and the case where the left hand is the left hand, depending on which hand is holding the main body, It is devised to select different operation tables. That is, in the configuration of the electronic book player 400 of the fourth embodiment, as shown in FIG. 10, in addition to the configuration of the electronic book player 100, the grip position detecting unit 401, the distribution storage unit 402,

The X and Y coordinates on the surface of the main body indicated by the above signals are different from the X and Y coordinates shown in FIG. The above-mentioned pressure-sensitive sensors are scattered only on the right side surface and the left side surface because the difference between the grip by the right hand and the grip by the left hand becomes apparent.

The distribution storage section 402 stores pressure distributions on the left and right side surfaces detected by the gripping hand information inputting means 401. This pressure distribution is shown in FIG. In the figure, squares indicated by reference signs b1, b2, b3, and b4 indicate coordinate positions on the surface of the main body, and numerical values in the squares indicate magnitudes of pressure at the coordinate positions. Right hand pattern table 403, left hand pattern table 40
4 describes the patterns of pressure distribution when the main body is gripped by the right hand and the left hand, respectively. Since these are used for the grasping hand determination by the left and right hand determination unit 407,
A standard one is selected. The right hand pressure distribution pattern and the left hand pressure distribution pattern are shown in FIGS. 13 (a) and 13 (b), respectively. Similar to FIG. 12, the quadrangle in the figure indicates each coordinate position on the surface of the main body, and the numerical value in the quadrangle indicates the magnitude of pressure at each coordinate position. FIG. 13 (a)
Is a pressure pattern for the right hand, so numerical values are described in the squares indicated by reference signs c1, c2, c3, c4, and c5 on the right side surface, and are not described in FIG. 13 (b). Since FIG. 13B shows the pressure pattern of the left hand,
Numerical values are described in the rectangles indicated by reference numerals d1, d2, d3, d4, and d5 on the left side surface, and are not described in FIG. 13 (a).

The first operation item table 405 is a table whose description content is exactly the same as that of the operation item table 107. As with the first operation item table 405, the second operation item table 406 describes state symbol strings and operation commands in association with each other.
The association in 06 is performed such that the direction of increasing or decreasing the number of pages is opposite to that of the first operation item table 405. FIG. 14 shows an example of the second operation item table 406. The correspondence in this figure is in the opposite direction to the example of the operation item table 107 shown in FIG. 6A, that is, the clockwise inclination of the short side of the main body is the direction of increasing the page number and the direction of decreasing the counterclockwise direction. It is what In this figure, the status symbol string "B
→ A → B ”corresponds to the operation command“ next chapter ”,
The respective status symbol strings "B", "D", and "D → E → D" correspond to the operation commands "next page", "previous page", and "previous chapter".

However, in the fifth embodiment, the manner of holding by each operator can be reflected in the status symbol table. I am devising. Therefore, in the electronic book player 500 according to the fifth embodiment of the present invention, in addition to the configuration of the electronic book player 100, as shown in FIG. 15, a summary table 501, a monitor period setting unit 502, a frequency data creating unit 503, a gate are provided. 504, maximum / minimum tilt angle calculation means 5
05 and a division angle rewriting unit 506.

The summary table 501 includes the status symbol table 10
The angle ranges obtained by further dividing the respective angle ranges of 3 are described. Further, the totalized value is counted in correspondence with these angle ranges. The angle range in the summary table 501 is referred to as an angle section in order to distinguish it from that in the state symbol table 103. FIG. 16 shows an example of the summary table 501. “+ 30 ° <ω ≦ + 40 °”, “+ 20 ° <ω ≦ + 30 °”, and “+ 10 ° <ω ≦ + 20 °” in the figure are angle sections, and cells h1, h2, and h3 adjacent to the angle range are included.
... are cells for counting the above aggregated values.

The monitor period setting unit 502 receives the setting of the monitor period by the operator. During the monitoring period, the monitoring period setting unit 502 closes the gate 504 and opens the gate 504 at the end of the monitoring period. Frequency data creation unit 50
3 determines which of the angle sections the A / D conversion result performed by the sampling section 102 belongs to during the monitoring period set by the monitoring period setting section 502, and increments the aggregated value of the determined angle sections. . After the monitoring period ends, the angle segment and the aggregated value generated on the aggregate table 501 are called frequency data. Numerical values shown in cells h1, h2, and h3 of FIG. 16 are total values obtained by totaling 450 times.

The maximum / minimum inclination angle calculating means 505 calculates an angle section in which the total value of the frequency data changes from increase to decrease and an angle section in which the count value changes from decrease to increase. The above angle divisions are called maximum divisions and minimum divisions. In the tabulation result of FIG. 16, there are six minimal sections g1, g2, g3, g4, g5, and g6. If the minimum classification does not reach the number of items in the status symbol table 103, the operator is requested to set the monitor period again.

The division angle rewriting unit 506 sets the state symbol table 10 so that the lower limit angle of the minimum division is divided.
Rewrite the angle range of 3. FIG. 17 shows an example of rewriting by the division angle rewriting unit 506. Angle range "-18
“0 ° <ω ≦ −60 °” is an angle range in which the lower limits of the minimum sections g1 and g2 are separated, and the angle range “−60 ° <ω”
".Ltoreq.-20.degree." Is an angle range in which the lower limits of the minimal sections g2 and g3 are separated.

As described above, according to the fifth embodiment, since the angle range table corresponding to the range of angles most frequently used by the user is created, the control according to the way of holding by the operator can be performed more. You can do it.
