An area information estimating device has a camera that photographs an image within a sensing area, a person detector that detects a person from the image from the camera, and a position calculator that calculates an existence position of the person in the sensing area based on a coordinate on the image in which the person is detected by the person detector. The person detector excludes the person in whom a relationship between the coordinate and a size on the image does not satisfy a predetermined condition from a detection target.

An ultrasonic wave receiver receives an ultrasonic wave outputted by an ultrasonic wave oscillator, and outputs a receiving signal. A level determining unit makes a determination as to the presence or absence of a sheet of paper based upon a level of the receiving signal. A CPU is informed of this determining signal through a processing unit. An oscillation peak detector detects a peak value of a transmission signal used for controlling an ultrasonic wave transmitter, which is transmitted from an oscillation amplifier. A receiving peak detector detects a peak value of the receiving signal received by the ultrasonic transmitter. The phase difference of the two signals is detected based upon the difference in count values of a loop counter between the timing in which the peak value of the transmission signal is detected and the timing in which the peak value of the receiving signal is detected. The number of times in which the phase difference has exceeded a predetermined range is counted by a determining counter, and when the count value exceeds a reference value, it is determined that a plurality of sheets of paper are superimposed. Thus, it becomes possible to positively detect a doubles feeding of sheets.

Sheet double feeding detector, method and program of such a device

An unintentionally overlapped condition in a paper sheet being transported is detected by making ultrasonic waves incident on its path and detecting a phase difference between the received ultrasonic waves and a predetermined standard phase. For detecting an overlap on the basis of this phase difference, a specified data item on the detected overlap such as a cumulative number of times an overlap has been detected is generated and one of a plurality of preliminarily defined levels corresponding to this specified data item is selected. The selected level is outputted. If the overlap is detected over an entire detection range of the paper sheet from its front edge to the back edge, however, it is concluded that there is no possibility of an unintentional overlap.

Timing marks are printed at the left and right of a data mark of a two-dimensional dot code. Whether or not the data mark exists is determined based on the position on the line connecting the centers of the timing marks at both ends at the left and right of the data mark.

An ultrasonic wave that is transmitted from an ultrasonic-wave transmitter is received by an ultrasonic-wave receiver through a sheet A reception signal is input to an extracting unit The extracting unit compares its phase with a phase of a reference signal output from a reference-signal reproduction unit It converts a phase difference therebetween into a signal having a level corresponding to the phase difference. The signal having a level corresponding to the phase difference is compared with a threshold value set in a threshold-value setter by a comparator When one sheet is fed, the comparator produces a signal of high level. When a doubles feeding occurs, it produces a signal of low level.

The information processing device includes a first device (,) supplied with power and a second device (,) supplied with power from the first device (,) when connected to the first device (,). The information processing device includes a detection portion (,-,-,-,-,) detecting the attachment/detachment of the second device (,) and a supply portion (,-,-,) supplying power to the second device (,), and the first device (,) includes a control portion (,) controlling the supply of the power by the supply portion (,-,-,) according to the result of detection by the detection portion (,-,-,-,-,). As the supply of the power by the supply portion (,-,-,) is controlled according to the result of the detection by the detection portion (,-,-,-,-,), the electric shock on an internal circuit of the second device (,) at the time of attachment/detachment of second device (,) can be prevented.
